Sep 29, 2021 · November, 2023: Global warming in the pipeline webinar November, 2017: Scientific Reticence: A Threat to Humanity and Nature. Jim Hansen/Pam Pearson/Philip Duffy press conference at COP-23 in Bonn, Germany on 10 November.

Since the late 1970s, he has focused his research on Earth’s climate, especially human-made climate change. Dr. Hansen is best known for his testimony on climate change to congressional committees in the 1980s that helped raise broad awareness of the global warming issue.

Hansen is best known for his testimony on climate change to congressional committees in the 1980s that helped raise broad awareness of the global warming issue. He was elected to the National Academy of Sciences in 1995 and was designated by Time Magazine in 2006 as one of the 100 most influential people on Earth.

Hansen also proposed an alternative approach of global warming, where the 0.7°C global mean temperature increase of the last 100 years can essentially be explained by the effect of greenhouse gases other than carbon dioxide (such as methane).

Jan 12, 2024 · Record global temperature in 2023 helps reveal acceleration of global warming on decadal time scales. The proximate cause of the acceleration is increase of Earth’s energy

Nov 2, 2023 · Our present paper addresses climate sensitivity and warming in the pipeline, concluding that these exceed IPCC’s best estimates. Response of ocean circulation and ice sheet dynamics to global warming—already outlined in the Ice Melt paper—will be addressed further in a later paper. The structure of our present paper is as follows.

4 days ago · Global warming has accelerated since 2010 by more than 50% over the 1970-2010 warming rate of 0.18 °C per decade Footnote 1 (Figure 1). Footnote 2 Earth is now warmer than at any time in the Holocene, the past 11,700 years of relatively stable climate in which civilization developed, and it is at least as warm as during the extreme warm Eemian interglacial period 120,000 years ago.

Nov 2, 2023 · Global warming may be happening more quickly than previously thought, according to a new study by a group of researchers including former NASA scientist James Hansen, whose testimony before...

Top climate scientist James Hansen tells the story of his involvement in the science of and debate over global climate change. In doing so he outlines the overwhelming evidence that change is happening and why that makes him deeply worried about the future.
